Pregnancy can be detected 13 to 14 days after the day of ovulation by using a test paper called a urine pregnancy test.
The test paper detects the concentration of human chorionic gonadotropin, or HCG, levels in the urine. After a woman’s egg matures and is discharged, the better time to conceive is 12 to 24 hours after ovulation, and if you have sex at this time, fertilization can be completed.
When the fertilized egg is formed, it can usually be deposited in the endometrium in 1 week, forming trophoblast cells that begin to secrete HCG. again, after 1 day, slightly elevated levels of HCG can be detected in the peripheral blood, and a weak positive can be detected 3 to 4 days later through the use of urine pregnancy test strips.
After detecting pregnancy, it is necessary to go to a regular hospital in time, improve the blood HCG, ultrasound and other related examinations, and make a clear diagnosis under the guidance of a professional doctor.
